Resistance 3 the degree to which a substance or device opposes the passage of an electric current, causing energy dissipation.

What is Analog? Analog electronic components work by varying the current of electricity The Arduino has a built in Analog to Digital converter. The ADC translates analog signal to a digital code. This is very important to textile sensors

analog input Use the analogRead function to read from an analog sensor We need load the value into a variable variable = analogRead(PIN); textileresistence = analogRead(buttonPin); be sure to declare your variables in setup int texe; texe = analogRead(10);

The trick to reading an analog input Analog Read requires an extra resistor. This resistor helps define 0V or 5V leaving no possibility for an empty reading. Leaving this out can lead to misinformation

Digital to analog Converter (DaC) One of the amazing things about Arduino is it’s ability to vary the output voltage on Pins 3,5,6,9,10,11 This allows us to dim LED’s or change the sound of a piezo (Music) Acceptable output signal levels 5V 0V 0.9V 4.2V HIGH LOW

How it works 3,5,6,9,10,11 Only on PINS 3,5,6,9,10,11 Blinking faster than the eye can see. It’s actually fake.
